such, for example, as those positions illustrated in dotted lines in Figure 1. If the auxiliary conveyer were merely swung about vertical drive shaft 27 as a fulcrum, it will be obvious that its discharge would fall wholly at one side of the center of the main conveyer. This would load the main conveyer unevenly and would be disadvantageous in the case of a threshing machine since one side of the cylinder only would be handling grain while the other side would be running idle. In order to avoid this objection, the above described arrangement is provided whereby the entire auxiliary conveyer may be shifted bodily laterally with respect to the main conveyer so that the discharge of the auxiliary conveyer may at all times fall directly upon the center of the main conveyer. This relation of the parts is also illustrated in dotted lines in Figure 1.

From the foregoing description, it will be apparent that I have provided a conveyer system in which an auxiliary conveyer may be formed either horizontally or vertically with I respect to a main conveyer and may be adjusted bodily in a lateral direction with respect to the main conveyer in order to maintain a proper delivery to the main conveyer in any position of the auxiliary conve yer and to maintain at all times a driving connection between the two conveyers.

I claim:

1. In a device of the character described, the combination of a pair of conveyers adapted for relative angular adjustment, and means extending transversely of one of said conveyers for adjusting the delivery end of the other of the conveyers bodily in a lateral direction whereby the discharge of said last mentioned conveyer may be directed substantially upon the center of the other of said conveyers, together withmeans for maintaining a mechanical driving connection between said conveyers in the said relative position thereof.

2. In a device of the character described, the combination with a main conveyer having a frame provided with a cross shaft operatively connected to said conveyer, of an auxiliary conveyer provided with a frame having a cross shaft ope'ratively connected to the auxiliary conveyer, swiveled yoke members connecting said cross shafts, and motion transmitting connections between said cross shafts including a shaft co-axial with the swivel of said yoke members, one of said yoke members being slidable longitudinally in the direction of its cross shaft, whereby the discharge of the auxiliary conveyer may be centered upon the main conveyer in any swiveled relation of said yoke member.

3. The combination with a main conveyer having a frame provided with a cross shaft and an auxiliary conveyer having a frame provided with a cross shaft, said conveyers being operatively connected to their respective cross shafts, of yokes in mutually swiveled relation connecting said cross shafts and arranged to support the auxiliary conveyer from, the main conveyer, one of said yokes being axially reciprocable upon thecross shaft to the main conveyer, a vertical shaft co-axial with the swivel between said yokes, gears upon said vertical shaft and pinions upon said cross shafts meshing with said gears, the pinion on the cross shaft of the main conveyer being splined thereto for sliding movement thereon with said yoke, said auxiliary conveyer being pivotally and let erally movable with respect to said main conveyer while maintaining driving connection therewith.

l. The combination with a pair of conveyers pivotally adjustable in horizontal and vertical planes, of means for moving said conveyers laterally relative to each other, said conveyers being provided with driving connections adapted to maintain a motion transmitting relation between said conveyers and any of the positions thereof possible by virtue of said movements.

5. In a conveyer system, a main conveyer, a main conveyer frame, an auxiliary conveyer, an auxiliary conveyer frame, a support on said main conveyer frame supporting said auxiliary conveyer frame, said auxiliary conveyer frame being pivotally mounted on said support for vertical and horizontal movement about said support, and means for moving said auxiliary conveyer slidably on said support for movement laterally of said main
